To ZZ whom it may con-cern:

Be it known that l, JOHN V. RUND, citizen of the United tates, residing at Pesotum, in the county of Champaign and State of Illinois, have invented certain new and useful improvements in. Trip Mechanism, of which the followingis a specification. K l My invention relates to new and useful improvements in tripping devices, and more particularly to trips employed in connection with` railways for lactuating, a brake or other safety operating appliance carried by locomotives, being a division of my co-pending application for an automatic railway appliance,'filed January 3l, 1913 and bearing the Serial No. 745,471.

The object of my invention is the provision of a trip which may be readily swung into and out of activeposition and whichmay be connected to the usual semaphore employed in signaling t ains, in order that the semaphore may be swung to danger position whenever the trip is swung to active 'position.

i further 'object of my invention is to provide means for swinging the trip and semaphore arm in and out of active or danger position simultaneously. And, a still further object of my invention is to provide a. trip which will gradually engage the mechanism to be tripped and thus avoid injury thereto.

`With these and other objects in view, my invention will be more fully described, illustrated in the accompanying drawings, and then specifically pointed out in the claims which are attached to and form part ot this application.

In the drawings -Fignre l is a transverse sectional view through a conventional trac-lr in connection with which my trip isemployed, showing the trip and its operating mechanism in elevation, the housing of the operating mechanism being shown in v`section. Fig. 2 is a sectional view on the line Q.-2 of Fig. l, further showing the construction and manner of mounting the trip. Fig. 3 is a perspective view or tre trip properf A Corresponding and lilie parts are referred to in the following descriptionand indicated in all the views of the accompanying draw ing by the same reference characters.

To insure a clear anderstanding1 omy trip mechanism I have illustrated saine in connection with a conventional track, in cluding spaced rails l0 carried by ties ll. The trip de ice proper, as leest shown in Fig.

3 of the drawings, comprises a longitudinaliy bowed body-member 12 having downso wardly depending parallel end-portions 13 and la provided with alined openings l5. The end portion la' is provided with a lateral extension 16 terminating; in an arm i? parallel to the end portion iabut offset. therefrom, the estensioni@ and arm l? in effect, forming a lever. arm for swinging the trip when the latter is mounted in place.

The trip is mounted in spaced parallel relation to one rail of the track by means of brackets 18 having reduced threaded ter ininals 19 which pass through bores formed in the web of the rail and which receive nuts 20 by which the brackets are secured in place. The opposite ends of the brackets, however, terminate in spaced arms 21 loetween which the end portions 13 and la of the trip are pivoted. pivot pins 22 being passed through the arms and the trip ends,

as shown in Fig. 2 of the drawings.

F rom the'foregoing description it will he apparent that-when the trip operating arm 17' is swung' in a vertical4 position, the lbowed or arcned portion l2 or the trip will he directed upwardly as shown in Figs. l and 2, the trip a whole, lying in a vertical plane paraliel to the plane of the adjacent rail. It will further he aoparent that the operating arm 3.7 'of the trip may be swung iinvardly and upwardly toward the rail to swing the trip to horizontal position. This trip. of coarse, is so proportioned that whenin the latter position itwili oder no obstruction to the passage of any train-can ried device which it is to engage when in active position. When in active position any tain-carried 'device which it is to trip wiil i strike against one end of the trip and ride upwardly over 'the howen portion or" the same and then down over the opposite end, loo

the action of the trip being only momentary.

In order to operate this trip to swing the same into and ont et active position, as required, preferably provide a housing 23 lo leading from directly heneath'tA e trip-operate-:l arm Li?" to any snitahle signaling station, conventionally shown iithin this station have provided an arcuate bracket 254 having spaced rack-teeth .26 for alc engagement by the spring-pressed pa-Wl 217' oi? a lisnddever 28 which is pivotally mounted intermediate itslengtli,v as shown at 29. 'llie free end of this hand-lever is pivntally connected to e' link 30 one end of which extends into the housing 23 and is pivotally connected to one erni of e bell-Crank Alever 3l.J wfn'ieli'is pivoted as at 32 Within the house; connecting rod 33 pivotall'y Vconnects tbe :ree arm of the lever 3l 'with Ithe freel endfof the operating erm 1'? of tiret-rip. lt will therefore; be apparenttliat when the 'operating leverZB is swung downwardly, its movement is 'transmitted through the link 3 0, lever 3l end eonneotingrod 33 to swing.

the trip' to 'active nosition' While when the operating' lever, 28 is raisedl the trip will bevssvung'in thel reverse direction, or to inactive position. l j

j. lo order to provide Ineens for displaying a to v`arn the 'engineer of nn epprqeeliing train that the trip is set in aetivenosition so tbe'the may stop the train J:- v l before@ reaching the trip, if desired, l provide e standard 35i carrying et its upper end e sv/ingingly mounted semaphore arm 35 having an'enguleriyqdl.y osed operatingg larm 36. 'A Connecting'roJ 37 *isv pivotully connected by one end with thel free end of thissenlepliore arm and by its opposite end to one arm of a bell-erank'lever 35 which is pivotellyfnionnted'Within thfehousing 23, as sliovzn'at 39. The opposite erm of this' y bellcran'li vlever is slotted, as shown 'at e0,

to seat adpin el carried by the f'eonnecting rod 33. lt will therefore be apparent that the movement o' tbe Cniieetingrod yin raising or lowering the trip will be'transinitted thro-egli tlie'iever 38 and connecting rod 87. to correspondingly raise or lower the 'semapliore errn,'tl{1e inovernent of the trip end erm being sinmltaneous.I t

From the foregoing: deleoriprtiontalren.in

lt will of Course be understood that various changes in details of construction may be made, Within the scope of the appended. claims, Without in the slightest degree departing from the spirit of my invention.

What I claim is:- `d1. A tripping device for operating traincarried "safety devices including a trip proper swingingly mounted upon a rail and movable about an axis parallel with the rail, means including a connecting rod for operating said trip, a pin carried by the connecting rod, a pivoted bell crank lever having'a slotted arm engaging said pin, a swingingly mounted semaphore arm, and operative Connection between said semaphore arm and the unslotted arm o f the bell-crank lever.

2. A tripping devioe'"`for operating traincsrried safetyt appliances, including a swingniglyeineunted trip, a swingingly mounted lever, a ben-Crank lever, a link connecting the' first lever and bell-crank lever, e oonnecting rod oining the bell-crank lever 'and tripe. pin carried by the connecting rod, a V

l'second bell-crank lever having a slotted arm Iengaging the pin, xa swingingly mounted semaphore arm, and a rod connecting the semaphore arm with tlie unslotted arm of the second bell-crank lever.

In testimony whereofv 4I aflin my signature in presence of twowltnessee.
